The particular case where it matters is the GPU node, which U-Boot 
manipulates. This revised patch version no longer renames the GPU node 
and so in practice avoids any issues that I'm aware of.

If there's a more general rule that node names are part of the ABI, then 
indeed we shouldn't take this patch.
